The Lowdown
G’day, Rusty here. We’ve got a solid run of surf coming up at Jaconé, but it’s one for the experienced crew only for the first few days. The water’s sitting at 73°, which is about average for this time of year – nothing out of the ordinary.
The week kicks off on Monday the 24th with a strong S swell pushing in at 8ft, 13-second period, combined energy of 2076 (moderate to strong). Wind’s ESE at 9 mph, so it’s cross-off and clean. This is solid, powerful surf and it’s only for those who know what they’re doing. Monday afternoon sees the swell bump up to 10ft with a 14-second period and energy jumping to 3234 – that’s some serious grunt. Winds ease to 6 mph cross-off, so it’s clean but big. Tuesday the 25th keeps the S swell going at 8ft, 14-second period, 2698 energy in the morning; wind is E at 9 mph cross-off. Still excellent for experienced surfers. Tuesday afternoon drops a touch to 8ft but the wind picks up to 12 mph from the east, still cross-off, making it a bit tricky.
Wednesday the 26th is a standout morning. Swell sits at 6ft from the S, 12-second period, moderate energy of 2039, but the wind goes completely glassy – zero mph out of the south. That’s as clean as it gets. This is your best session for pure quality if you’ve got the skills. Wednesday afternoon has the swell lifting again to 8ft, 15-second period, 2873 energy, but the wind is cross-off from the ESE at 9 mph.
Thursday the 27th delivers another top morning. Swell is 7ft from the S, 14-second period, 2024 energy, with a clean NE offshore wind at 16 mph. That’s proper offshore, groomed conditions. Thursday afternoon goes glassy again – wind from the east at just 3 mph, swell at 7ft S, 14-second period, 1792 energy. Two glassy windows in a row. Friday the 28th sees the swell drop: 4ft S, 12-second period, 580 energy in the morning with a light ENE offshore. Still clean and fun, but notably smaller.
Saturday the 29th shifts direction. Morning brings 6ft from the ENE, only 8-second period, 637 energy, with a NE offshore at 6 mph. It’s a shorter-period windswell, but clean and surfable. Saturday afternoon drops further to 4ft, 9-second period. Sunday the 30th gets a bit lumpy in the morning: 8ft from the ENE, 9-second period, 982 energy, but the wind is cross-onshore from the WSW at 9 mph, so it’s choppy. Sunday afternoon improves with 6ft ENE, 9-second period, 655 energy, and a light cross-off from the ESE.
From Monday the 31st onward, it gets messy. Onshore winds, small weak swells, and poor conditions dominate until Thursday the 5th of September. There’s a gap of several days where the surf is ordinary at best – mostly onshore, choppy, and small. Thursday the 5th afternoon brings a clean offshore wind from the ENE at 12 mph with a 3ft SSE swell, 10-second period, 205 energy – rideable but small. Friday the 6th is tiny: 2ft SSE, 10-second period, 117 energy in the morning with a gentle offshore, then fading to 2ft by Monday the 8th. Tuesday the 8th morning offers a late bright spot: 5ft SSE, 8-second period, 582 energy with glassy conditions – clean little waves if you’re keen, but it’s a long way out.
The clear standouts are Wednesday the 26th morning and Thursday the 27th morning, both with glassy or clean offshore winds and solid S groundswell. If you’re experienced and can get out there, those are the sessions to aim for.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
